Abstract

A head worn display (HWD) includes a head attachment region, an internal display and a controller. The internal display is viewable by a user and includes variable transparency areas. The internal display is arranged to display at least a portion of an external region external to the HWD. The controller is configured to control the variable transparency areas to block view of a region of the external region and to control the internal display to overlay information in a region of the internal display corresponding to the region of the external region which is blocked.
